This escaped our notice, until URR brought us up short:
If the United States, and in particular the United States Navy, has any sense of true ‘strategic messaging”, we will let the rest of the world know that, should another small craft ignore similar warnings, it, too, will be fired upon. And any death or injury that results from such incidents is the responsibility of those who willfully ignore the warnings, and on those who likely have sent them.
Strategic messaging, indeed. Let the message go out, loud and clear.
